its will be seen from the drawing, aiter tee coal it has oeen removedthe stratum oi siate i4: is left substantially unsupported; L great dealoi? trouble has been caused by this slate hecon'iinn' in whole or in.part severed from the root oil the mine ant lling into the chamber. incertain. forms of mininn; the coal and sin e are brought down together,and this, of course, necessitates a subsequent separation of the two inother forms the attem t is to remove the coal first, and to care for theslate subsequently by various means, all of which has involvedconsiderable labor, inconvenience and expense. Where a machine of thetype shown is used, it will be seen from Fig. 1 of the drawing that eachcut of the severing device leaves an overhanging portion of the coal,shown at 22 in Fig. 1 of the drawing, havin an arched formation, andthus adapted to orm a support f6r the portion of the roof extending overthe severing device or operating portion of the machine. This permits ofremoval of the coal without its becoming mixed with the draw slate fromthe roof of the mine, but when the machine has been moved forward and asecond cut taken the support is removed from the portion of the roofback of the cutter, and the slate is then likely to fall from thisportion of the roof. To'take care of this falling slate, the presentinvention provides for a platform consisting of side rails 23 carried byuprights 24 positioned at each side of the mine chamber. The uprights 24are slidably mounted in standards 25 held in position by a cross bar 26extending from one side of the chamber to the other. Any suitable meansmay be provided for raising and lowering the uprights 24. In the drawingI have shown these uprights provided with racks 27, which are arrangedto mesh with pinions 28 carried on the shaft 29, and driven by a wormwheel 30 which meshes with the worm 31, which is in turn driven by amotor 32. The adjustin mechanism for the uprights 24 is provide induplicate, there being one set at each side of the mine chamber. The

standards 25 on each side of the mine chamher are aced apartlongitudinally by bars 33, whic h extend from one of these standards tothe other along the side of the mine chamber. The tracks 23 are spacedfrom one another transversely by a plate or beam 34, which extendsacross the mine chamber from one of these tracks to the other, and holdsthem in fixed relation relatively to one another.

The tracks 23 are higher at their forward end, as shown in Fig. 1, thanat the rear end, and a table 35 is mounted for reciprocation along thetracks 23, and is supported thereon by a series of rollers 36. Securedto the lower side of the table 36 is a downwardly extending lug orprojection 37 which has pivotallv secured thereto at 38, a pitman rod39, which is driven by a crank 40, arranged to be rotated by a motor 41mounted on the cross plate 34. It will be ap arent that the operation ofthe motor 41 wi l transmit a reciprocatory motion to the table 35. Theupper surface of the table 35 is provided with a series of transverserid 42 which, as shown in the figure, are given an inclination to therear or lower portion,

of the table. Blocks of material, such as shown at 43, when detachedfrom the roof of the mine will fall upon the table 3."), and willgradually be moved to the rear or lower portion of the table as thetable is reciprocated by the motor 41, in a way which will be apparentfrom the figure. Extending longitudinally of the table, at each sidethereof, and arranged to support the same, is a pair of beams 44, andthese beams have pivoted thereto, at the real or lower end, thedownwardly swinging doors 45. A latch 46 is provided for holding thedoors in their upper position, and a pair of chains 47 limit thedownward movement of these doors to give them an inwardly slopingosition when lowered, as shown in Fig. 2. he material which falls uponthe table 35 gradu: ally works backwardl and downwardl to a position ontop of tie doors -15, and t ere is collected until the latch 46 iswithdrawn and the doors permitted to drop. The material will then bedischarged into the car 22', being uided to a position over the car bythe slope of the doors in their lowered position. Secured to the forwardend of each of the rails 23 is a forwardl and upwardly directedextension 48. hese extensions carry a cross bar 49:11. their upper end.The extensions 48 are of the proper length to bring the cross bar 49into contact with the roof of the mine at a position substantially atthe end of the last out made by the severing device 17 when the machineis positioned for starting a new cut. l'n this way the cross bar 4!)cooperates with the arched extension 22 of the material being mined, tosupport the roof of the mine directly over the opcrz'iting position. Thebar is 'lorcibly pressed into contact with the roof by the rack andpinion device for adjusting the position of the uprights 24.

From the foregoing description it is thought that the operation of thedevice will be easily understood. When the machine is properlypositioncd'in the chamber for making a cut, the uprights 24 aresuitablyadjusted by means of the motors 32 with their connecting gearing, tobring the cross bar 49 firmly into contact with the roof of the mine ata 1point where it will just clear the severing evice when it reaches theupper end of the next cut. The severing device is then operated, and thecoal which is severed is carried back and discharged onto the car 22.During this operation the table :15 is in position to intercept anymaterial that may become detached from the roof of the mine, and usuallypractically all of the draw slate found between the coal and the upperstratum of rock will fall down by its own weight onto this table, whereit will be worked backwardly by the reciprocatory movement of the table,and be collected on the doors l5.
